<p>Binary composition (I) comprises 2,3,3,3-tetrafluoropropene and ammonia. Independent claims are included for: (1) heat transfer composition comprising the composition (I) and one or more additives comprising lubricants, stabilizers, surfactants, tracer agents, fluorescent agents, odorous agents, and/or solubilizing agents; (2) heat transfer installation comprising a vapor compression circuit containing the composition (I) as a heat transfer fluid or a composition containing the heat transfer composition; (3) a method-I of heating or cooling of a fluid or a body by means of a vapor compression circuit containing a heat transfer fluid, comprising: successive evaporation of the heat transfer fluid, compression of the heat transfer fluid, condensation of the heat transfer fluid and expansion of the heat transfer fluid, where the heat transfer fluid is a composition (I); and (4) a method-II of reducing the environmental impact of a installation for transferring heat comprising a vapor compression circuit containing an initial heat transfer fluid, comprising: a step of replacing the initial heat transfer fluid in the vapor compression circuit by a final transfer fluid, where the fluid transfer has a global-warming potential less than the initial heat transfer fluid, and the final heat transfer fluid is a composition (I).</p> |
